We divide 864666 by 16
We're looking to find how many times 16 goes into 864666.

Advancing to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 16

Going ahead to step 2:
16 can be fit into 86 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 80 from 86 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

Moving on to step 3:
The number 16 fits into 64 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 64 from 64 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 16

Going ahead to step 4:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 540.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 16

Going ahead to step 5:
The number 16 fits into 66 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 5404.0
Deduct 64 from 66 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 16

Going ahead to step 6:
When dividing 26 by 16, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 54041.0
If we take 16 away from 26, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
16 goes into 100 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 54041.6
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
16 goes into 40 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 54041.62
Subtracting 32 from 40 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 54041.625
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 54041.625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54041.625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 54041.625 with a remainder of 0.0.
